The ten essays in Future Challenges of Cities in Asia engage with some of the most critical urban questions of the near future across Asia. These comprise socio-economic and cultural transitions as a result of urbanization; environmental challenges, especially questions of climate change, natural disasters, and environmental justice; and the challenges of urban infrastructure, built form, and new emerging types of urban settlements. The essays demonstrate that it is increasingly difficult to conceptualize the 'urban' as one particular type of settlement. Rather, it would be more accurate to say that the 'urban' characterizes a global transition in the way we are beginning to think about settlements. This book is of interest not only to researchers interested in comparative and inter-disciplinary research, but also to urban practitioners more broadly, illustrating through concrete cases the challenges that urban regions in Asia and beyond are facing, and the various opportunities that exist for dealing with these challenges.

Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, which within seconds release energy comparable to what the Sun releases in its entire lifetime. The field of GRBs has developed rapidly and matured over the past decades. Written by a leading researcher, this text presents a thorough treatment of every aspect of the physics of GRBs. It starts with an overview of the field and an introduction to GRB phenomenology. After laying out the basics of relativity, relativistic shocks, and leptonic and hadronic radiation processes, the volume covers all topics related to GRBs, including a general theoretical framework, afterglow and prompt emission models, progenitor, central engine, multi-messenger aspects (cosmic rays, neutrinos, and gravitational waves), cosmological connections, and broader impacts on fundamental physics and astrobiology. It is suitable for advanced undergraduates, graduate students, and experienced researchers in the field of GRBs and high-energy astrophysics in general.
